LAB COATS - COLLECTING AND RETURNING THEM
Everyone taking a practical module is issued with a coat, and that coat stays with you until the module ends. Collect yours from the technicians' office in the first week. You will be asked for your student number rather than your name. Two of you share a name this year, and the confusion that caused last year took a month to untangle. Coats come back washed. We have no laundry here, and a coat returned in the state it left the greenhouse in will be handed straight back to you. Tell us before the end of term if you lose one. The replacement charge is lower than the fee for a coat that is simply never returned, and that fee is applied automatically.
